Something like
command_not_found_handler() { test -x $1.sh && $1.sh $@[2,-1] }
should do the trick.

Cool, I tend to use .zsh, but mostly so I know they're not system scripts.

Leaving out the .«tab» saves a little bit of typing. But you might have
already fully tab-completed a couple chars in.

You could tie into the command_not_found_hook (briefly mentioned in
zshmisc(1)). Something like this:
command_not_found_handler() {
actual=$@[1].sh
print "Proxying for actual: $actual"
for p in $path; do
if [[ -x $p/$actual ]]; then
$actual $@[2,-1]
break
fi
done
}
Then use:
% foo aa bb
Proxying for actual: foo.sh
<regular output>...
A couple caveats:
* I don't actually do this, but maybe I'll try; the func is not really
tested
* zsh syntax highlighting
(https://github.com/zsh-users/zsh-syntax-highlighting) won't match foo
* running in cwd as ./foo isn't handled
* not sure if looping over path is best approach; would something with
hash work?

Mine are all in ~/Dropbox/bin/ (which I've added to $PATH) so I know
they aren't system scripts, and since my Dropbox only syncs between
Macs I don't have to worry about cross platform script compatibility
but I always have all of my scripts on all of my Macs :-)

Yup, I use 'tab' whenever possible to autocomplete. The problem is
that I have recently converted some functions (which did not have
".sh" suffix) to scripts, mostly so I can call them from other scripts
without putting them into .zsh(rc|env) but 'muscle memory' keeps me
typing them the old way.

FYI this worked perfectly for me, and I love the touch of having it
remind me that this is catching me when I type something incorrectly,
which is more likely to help me remember to do it correctly in the
future. I think. Theoretically. I definitely like what it does,
regardless of its actual effect on my habits.

Worked as expected for me.

I don't use that but now I'm going to head over and see what else is there :-)

It is extremely unlikely that I would ever do `./foo` anyway.

It was certainly fast enough for me that I wouldn't spend time trying
to optimize it. Even if it was slow it would be another way that maybe
it would push me towards correcting my habit of mistyping.
Thanks again.

command_not_found_handler
Yet another reason Zsh is amazing.
Thanks to everyone who took the time to reply. "command_not_found_handler"
is pretty much exactly what I was hoping for.
